Most requirements for an autonomous colony on Mars can be fulfilled today, thanks to the experiences with manned orbital stations (ISS) and recent robot missions to the Red Planet. Also, there is advanced mining and recycling technology available. So, there are problems and solutions. But there are some crucial issues listed on this page that might not find a solution at all, at least not today. Each of these issues can be a fundamental blocking point in the plan to make a colony independent from regular replenishments.
Issue 1: Energy
Energy is required to produce return fuel, food production, lighting and local goods production. The simplest available energy source seems to be solar power, but it has several serious limitations on Mars. Robert Zubrin is an advocate of geothermal, which as a bonus could provide water for a colony. Nuclear fuels could be brought from Earth, for a small cost in mass. The net energy gain under Martian environmental conditions for solar panels is well known and has been tested extensively by the Mars rovers.
See Cost of energy on Mars for more information.
Issue 2: Money
The financial effort estimation reveals the high costs for the transport to the Red Planet. Establishing a whole colony requires many shipments. Both private fund raising and government programs are based upon a broad public interest. Enough people must be convinced to support the enterprise. To overcome this problem the Mars One project tried to raise the money from selling of TV rights, but went broke in 2019.
In the last 10 years SpaceX has dropped the cost to orbit ten fold. If the Starship & Heavy-booster achieve their goal of 100% reusable space craft with fast turn around, then the cost will likely drop another ten fold. This makes Mars exploration effectively 100 times cheaper.
Issue 3: Health
A number of health problems due to low gravity might compromise the viability of a martian settlement. One expensive solution to low gravity is to use a centrifuge.
